This article presents a current (as of September 2019) list of recommended ages for proven
terrestrial impact structures (n= 200) and deposits (n= 46) sourced from the primary …

Over the past few decades, it has become increasingly clear that the impact of interplanetary
bodies on other planetary bodies is one of the most ubiquitous and important geological …

Accurate and precise dating of terrestrial impact craters is a critical requirement for
correlating impacts with events such as mass extinctions. A number of isotopic systems have …

High-resolution electron backscattered diffraction (EBSD) and correlated in situ secondary
ion mass spectrometry (SIMS) U–Pb geochronology have been conducted on impact …

Accurate age determination of impact cratering events remains difficult and controversial.
Less than a quarter of all documented impact craters are regarded as accurately and …

Large impact structures have complex morphologies, with zones of structural uplift that can
be expressed topographically as central peaks and/or peak rings internal to the crater rim …

Terrestrial impact structures provide the only analogs for hands-on astronaut training or
robotic exercises in preparation for fieldwork on other planetary surfaces. Impact structures …

Abstract Single crystal (U‐Th)/He dating has been undertaken on 21 detrital zircon grains
extracted from a core sample from Ocean Drilling Project (ODP) site 1073, which is located …

The recently published Lethaia paper by Bergström et al.(https://doi. org/10.1111/let. 12269)
on the age of the Ordovician Winneshiek Shale (Iowa, USA), and the impact that formed the …

Abstract Single-crystal (U-Th)/He dating of 32 apatite and zircon crystals from an impact
breccia yielded a weighted mean age of 663±28 ka (n= 3; 4.2% 2σ uncertainties) for the …
